Researchers synthesized fourteen new metal-ciprofloxacin complexes using aromatic polycarboxylate ligands. These novel metal-quinolone complexes represent the first of their kind containing aromatic polycarboxylate ligands and extended polymeric structures.

Area of Science:

  • Coordination Chemistry
  • Materials Science
  • Crystallography

Background:

  • Ciprofloxacin (cfH) is a widely used fluoroquinolone antibiotic.
  • Metal complexes can exhibit unique structural and functional properties.
  • Aromatic polycarboxylates are versatile ligands for constructing coordination frameworks.

Purpose of the Study:

  • To synthesize and characterize novel metal-ciprofloxacin complexes.
  • To explore the structural diversity of these complexes using various metal ions and aromatic polycarboxylate ligands.
  • To investigate the potential for forming extended polymeric structures.

Main Methods:

  • Synthesis of metal-ciprofloxacin complexes under basic conditions or with aromatic polycarboxylate ligands.
  • Structure determination using single-crystal X-ray diffraction.

    • Main Results:

    • Fourteen new metal-ciprofloxacin complexes were successfully synthesized and structurally characterized.
    • Compounds 1-9 represent the first metal-quinolone complexes incorporating aromatic polycarboxylate ligands.
    • Compounds 10-14 exhibit two-dimensional rhombic grids with large cavities (13.6x13.6 Å), and polymeric extended metal-ciprofloxacin complexes were reported for the first time.

    Conclusions:

    • The study successfully demonstrated the formation of diverse metal-ciprofloxacin complexes with varied structural architectures.
    • The incorporation of aromatic polycarboxylate ligands led to novel coordination compounds, including the first reported metal-quinolone-polycarboxylate complexes.
    • The discovery of extended polymeric metal-ciprofloxacin complexes opens new avenues for materials design.
